城市地下空间排水系统设计要点分析

Analyses for the key points to designing the drainage system of the urban underground space

城市地下空间各类排水系统的水质、水量有不同的特点,设计时要根据项目情况,选择适用的提升设备,制定合理的收集、处理、排放方案。本文归纳了城市地下空间常见排水类型,分析了各排水系统的设计原则、设计要点及优劣性,以期对设计、施工、管理等工程实践活动提供一些思路。

Since the quality and quantity of the sewage from various drainage systems of the urban underground space are quite different,urban sewage lifting equipments should be selected appropriately,and a reasonable plan for the treatment, disposal and discharge of the sewage should be made according to the specific condition of the project.The common drainage types were summarized; the design principles and key points,advantages and disadvantages of various drainage systems were analyzed in order to provide some new ideas for the practical engineering activities such as design, construction and management.
